Specification of Letters Patent.

- Patented July 27, 1909.

Application filed April 15, Serial No. 427,123.

To all whom it may concern. Be it known that I, NAPOLEON PLOUFF, a subject of the King of Great Britain, residing in West Brookfield, in the county of Worcester and State of Massachusetts, have in vented certain new and useful Improvements in Windows, of which the following is a specification.

This invention relates to that class of windows in which one or more of the sashes are removable and in which the lower sash is adaptedto swing out of a vertical position and be sustained in an inclined or non-vertical position: and it." consists in a certain novel construction and arrangement of parts whereby the sashes can be removed, as for cleaning purposes; whereby the lower sash can be swung mward, thus causing the air whichimpinges against it to be deflected upward into the room; and whereby it can be secured in both its normal and its inwardly inclined positions.

The nature of'the, invention is fully described below, and illustrated in the accompanying drawings, in which: I

Figure 1 is an elevation of a window and easing thereof looking from the inside, the parts beingin their normal position. F g. 2 s a section taken on line 22, Fig. 1 with the lower sash swung toward the room. Fig. 3

is a rear elevation in enlarged detail of one of the lower corners. Fig. 4 is an enlarged detailin vertical section t ken at the same corner. Fig. 5 is an enlarged detail in vertical section taken ,at the point where the upper and lower beads'on one of the jambs meet and are secured together.

Similar. characters of reference indicate corresponding parts.

Reference character 10 represents the lintel, 11 the jambs, 12 the sill, and 13 theoutside beads of a window-frame.

14 is the upper sash. This sash is not secured to the frame of the window, nor connected therewith by any cord'and pulley, and rests upon two u right posts 15 which are secured to the jam s directly under said sash, said posts being next the rear surface of the stiles 16 of the lower sash. The upper rail 17 of the lower sash is constructed as usual, and is, when the upper sash is in normal position, in front of the lower rail 18.

The lower corners of the rear side of thelower sash are beveled at 19, as illustrated in Fig.

flush with the surface thereof and are secured thereto bysuitable screws 21 above the beveled portions 19 and extend down opposite and behind said ortions to the outer portion 12'' of the sill, eing preferably curved or bent inward at their lower ends. These springs bear against the front edges of the posts 15, and their object is described below.

The lower sash is hung by means of suit.- able cords 22 and weights, and its movementor run is between the up er sash the stationary inside head 23 and between the posts 15 and the swinging lower inside beads 24. It will be seen that instead of a single stationary front bead secured to each jamb, there are two beads, one directly above the other. The lower ends of the u per stationary beads 23 are beveled u war andinward, and the upper ends of't e swinging lower beads 24 are correspondingly beveled. The lower ends of the swinging beads are pivoteonneeted with the two j ambs by means of headed pins or screws 25 which extend from the jarnbs through diagonal slots 26 formed in said lower swinging beads near their lower ends, said slots extending upward toward the inside of the window. The

lates-27. The upper ends of the swinging beads 2.4 are reinforced by lates whose vertical portions 28 are secure to the inner surface of said beads, and whose horizontal portions 29 are secured to the upper beveled ends of the beads. Spring-pins 30 extend horizontally inward from the upper ends of the beads through the portion 28 of said plates 28, 29. The upper stationary beads 23 are provided on their inner faces at their lower ends with plates 3 1 secured to said faces and extending for a short distance below the same, their lower edges being parallel with the lower edges .of the beads, and being pro vided with notches 32 in which said springipins 30 lie normally, thus locking the adjacent ends of the beads,23and 24 together, "the portion 28. of the plate on the head 24 being provided'with a suitable slot 33 (Fig. 5) into which the s ring-pin may be ressed down in order to isengage it from t e slot 32. Behind the plates 31 atthe loner outer pulleys 34 for the accommodation ofrthe cords 22. One of the stiles 16 of the lower sash is provided with a horizontal sprin bolt 35 which looks the said sash norma' y in a vertical position, by extending into .a

sides of these slots are reinforced by suitable corners of the beads 23 are located suitable hole 36 in one of the jambs 11, another hole being arranged to receive the bolt when the lower sash is swung outward in the position indicated in Fig. 2.

In practical operation, the (parts being in a angle, swinging before it the lower beads 24 which are allowed to swing by reason of the pivots 25 and slots 27 near their lower ends and by the inclined adjacent edgesof the upper and lower beads. When in this positlon, the sash rests on the beads 24, the

re es 22 being long enough'to permit of an a equate forward swing. In this position the lower sash deflects the entering air upward and revents a direct draft on the occupants of t e room, or the sash may be entirely lifted out by detaching the ropes 22, for washing or other purposes. Moreover by arranging suitable holes in the jamb in the ath of movement of the bolt 35, it may be ocked at any desired angle. While the lower sash is in the position illustrated in Fig. 2, or while it is entirely removed, the upper sash can be lifted off the posts 15. and be removed from the window, as it is not se cured to the jambs in any manner. While the lower sash is being swung forward, the springs 20 are forced by the posts 15 into the recesses 19, said recesses cutting off the corners of the sash at those oints and thus allowing the sash to swing fi'ee of the posts 15. When the lower sash is in its normal position the springs 20 press against the said posts and kee the window rain-tight at those oints. When the sashes are in their norma position, the lower sash is locked and prevented from either.vertical or swinging movement, by the bolt 35 and the springcatches 30; and the upper sash is prevented from vertical and inward movement by the posts 15 and the lower sash.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

In awindow of the character described, a

frame, an upper sash, stationary beads secured to the j ambs in front of the up er sash, plates secured to the inner faces of the lower portions of the stationary beads, the lower edges of said lates being beveled and extending down eyond the lower ends of the stationary beads and provided with notches in said edges, a lower sash, beads pivotally secured near their lower ends to the jambs in front of the lower sash and (provided at their in the upper plate thereby locking the upper and lower beads together, and adapted to be swung down out of engagement with the upper beads into the recesses in the lower beads whereby said lower beads may be swung inward toward the room, for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two" subscribing witnesses.
